The 25T-250-6-1/2 is a 2-1/2" Temperature Swichgage®. This very popular design features a diaphragm-actuated, temperature-indicating gage, with a built-in electrical switch for tripping alarms and/or shutdown devices. This model has a 6 foot capillary length with a standard 1/2-14 NPT threading, and a temperature range from 130-250°F (54-121°C).

The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument. This vapor actuated gage features a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against the diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gage reading.

Inside the 25T-250-6-1/2, the gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contact(s) are grounded through the Swichgage® case. This gage has a self-cleaning motion to enhance electrical continuity.

The EL150K1 Liquid Level Swichgage® instrument is a combination liquid level gauge and low limit switch. It can be used to monitor lube oil, hydraulic fluid or diesel fuel reservoirs and activate alarms and/or shut-down at a predetermined minimum level.

The L129 Lube Level Swichgage® instrument is a combination lube level indicating gage and adjustable low and high limit switch. It provides protection against low oil level or high level caused by overfill or fuel or water seepage into the crankcase.

The L129CK1 Lube Level Swichgage® instrument is a combination lube level indicating gage and adjustable low and high limit switches. It provides protection against low oil level or high level caused by overfill or fuel or water seepage into the crankcase.
